摘要
汾西矿业集团正令煤业井下巷道为深部软岩巷道,井巷严重损坏变形,巷道顶板离层、喷层脱皮,两帮收缩、底鼓现象普遍。在分析了巷道破坏原因的基础上,提出了采用O型拱支护技术方案,并进行了工业性试验,取得了明显的经济效益和安全效益。
The underground tunnel of Zhengling coal mine in Fenxi mining group is deep soft rock tunnel, the tunnel seriously damaged and deformed, roadway roof separation, spray layer peeling, two sides contraction, heaving floor phenomenon is general. On the basis of analyzing the roadway support technology scheme, and carries out the industrial test, and benefits damage reason, puts forward using 0 type arch achieved obvious economic benefits and safety
